Curiosity and awe have greeted a complete lunar eclipse, the longest one of this century and visible in much of the world.

The so-called "blood moon," when it turns a deep red, was visible at different times in Australia, Africa, Asia, Europe and South America when the sun, Earth and moon lined up perfectly, casting Earth's shadow on the moon.

The total eclipse lasted 1 hour and 43 minutes, with the entire event lasting closer to four hours.

Across Africa people turned to the sky, watching the reddish shadow slide up the moon's surface. In Somalia, some hurried to mosques for special prayers. In South Sudan, some dared to take photos in a war-torn country where using a camera in public is discouraged.

In Ethiopia's capital, Addis Ababa, people at an open-air restaurant admired a rare clear view during the rainy season, comparing a live NASA webcast to what they saw above. Then clouds rolled in.

"Dem yelebesech chereka," some murmured — Amharic for "blood moon."

"The reason that the moon turns red is because atmospheric scattering causes red light to pass through the atmosphere and the composition of the atmosphere can change if volcanic eruptions or forest fires occur," said Tom Kerss, an astronomer with the Royal Observatory Greenwich.
